Construction layout for underground caverns in nuclear island powerhouse of underground nuclear power plant

Abstract

A construction layout for underground caverns in a nuclear island powerhouse of an underground nuclear power plant, including: two primary caverns accomodating nuclear reactor powerhouses, combined caverns, electric powerhouse caverns, pressure relief caverns, a first primary traffic tunnel, a second primary traffic tunnel, a third primary traffic tunnel, a top adit system, a ground adit system, secondary traffic tunnels, and a side traffic tunnel. Each combined cavern and each electric powerhouse cavern are disposed at two sides of each primary cavern, respectively. Two combined caverns are in end-to-end connection and the arrangement direction of the two combined caverns are in parallel to the connecting line of the medial axes of the two primary caverns. Each pressure relief cavern is disposed between each combined cavern and a corresponding electric powerhouse cavern.

AI Technical Summary

Benefits of technology

The modularized layout reduces construction time and costs, enhances safety, and allows for efficient construction by minimizing the number of construction channels and ensuring stability, making the process more economical and convenient.

Problems solved by technology

Conventional construction layouts for caverns of an underground nuclear power plant leave much to be desired.

In general, the distribution of the caverns is irregular, which means that parts of the terrain are heavily excavated posing hidden risks.

In addition, the random distribution of the primary caverns adversely affects the construction of adits.

This delays the construction time and increases the investment cost.
